Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional cooling method is used, then device structure is simple, but cooling rate is slow
Solution Approach 1:
The cooling system is segmented into multiple independent components: cooling fluid supply holes in sidewalls, empty spaces for fluid circulation, discharge holes, and a rotatable fan. This segmentation allows each component to perform its specific function efficiently, achieving high cooling rates while maintaining reasonable structural complexity
Solution Approach 2:
The cooling fluid is supplied through sidewalls rather than from below, utilizing the lateral dimension for heat removal. The empty spaces create three-dimensional fluid circulation paths within the heat block, enhancing cooling efficiency by utilizing spatial dimensions beyond simple bottom-up heat transfer
2Loss of time
If cooling fluid supply system is added, then cooling speed increases, but device complexity increases
Solution Approach 1:
The cooling fluid supply system is merged with the existing heat block structure by integrating supply holes and empty spaces directly into the heat block body. This integration allows the cooling function to be added without requiring completely separate cooling apparatus, thus reducing overall device complexity while achieving faster cooling
Solution Approach 2:
The cooling system uses a rotatable fan to generate airflow that automatically circulates cooling fluid through the empty spaces and supply holes. The fan's rotation creates its own airflow pattern, eliminating the need for complex external airflow control systems and reducing device complexity while maintaining high cooling speed
